Huge thank you to King of Sound for being honest and actually taking the time to diagnose my issue…read morecorrectly. After replacing my car battery, my entire sound system started acting up. My bass knob stopped working properly, the bass sounded weak, and everything felt off. Another shop charged me $35, told me my amp channel was burnt out, blamed a small hole in my subwoofer, and immediately tried to sell me over $420 in new equipment without even checking or resetting my settings. I came to King of Sound for a second opinion, and within less than 15 minutes they figured out the battery replacement had simply reset my audio settings. They retuned everything, made sure the system sounded right, and now my setup works perfectly again -- honestly better than before. The best part was they were professional, patient, and genuinely wanted to help instead of upsell me on things I didn't need. They didn't even charge me. It's rare to find businesses that are this honest anymore. Definitely earned my future business and recommendation.

They didn't complete the service the day of the transaction; following day went back to finish the service. Big guy sitting in the desk told my husband that the "part of the transaction never went through" (OUR bank statements say otherwise) and that he needed to charge him again. He charged him again also adding $350 for tint job that he promised would be $250 total since he "really liked" my husband... that was just false advertisement for us to spend our money there! The system that they installed went out within a week!!! BC the the incorrect wires were used.. they set the system up to fail just to get more money! Anyways they stated that we had warranty as well if anything happened... husband went back in to get it fixed under " warranty" but instead left with another charge of $900+ for the new system... mind you they never finished the tint job as well .. bc "no time" Not to mention, they broke the back panel of the car when doing the installation didn't bother, giving us a discount or addressing the problem Really wish we would've read the yelp reviews before spending any dollar there!! I don't recommend them! They're very unprofessional bad with time management! You could tell their business is failing just by the way they come up with random amounts to charge you! And by the lack of cleanliness in the store itself !! In total, we spent around $2700+ !!! Just to have a boof system and half ass tint

I returned a couple of weeks later to have my stock radio replaced with a kenwood and get a dashcam installed in an older European sedan. Francisco and his team did a great job. The install was done on time on a busy Saturday. Overall, a very happy customer. I am now able to make hands free phone calls while driving. I plan to return in a few weeks for a dashcam install in another vehicle. I highly recommend Glendora Auto Sound for all your auto sound / dashcam needs. Cheers !!

I needed to install the dashboard screen (aftermarket head unit) installed for my parents' Honda Civic and found Custom Audio Design through Yelp. After reading the reviews, I decided to give them a try and I'm really glad I did. Art and his team were incredibly helpful from start to finish. He provided a free estimate upfront and clearly explained the options, pricing, and what would work best for our car no pressure, just honest guidance. The installation itself was smooth and professionally done, and the new system works great. What really stood out was the level of service after the install. My parents had a bit of a learning curve with the new screen, and Art took the time to patiently walk them through everything until they felt comfortable. In terms of value, I felt the pricing was fair for the quality of work, clean install, and customer service we received. It didn't feel like a rushed job they actually care about doing it right and making sure you leave confident using your system. Overall, a great experience. Everything is working perfectly thanks to Art and his team. I would definitely come back and highly recommend them to anyone looking for car audio or dashboard upgrades.
